Just got a new set of TB-14 rims and within a few days of use, my shimano 105 brake pads were mucked up with metal, including a 1-2 mm deep pit full of aluminum. Even the areas that werent pitted had aluminum dust all over them. before using them on the new rims, i sanded the brakes down with fine grit to a very smooth finish, so I was a bit surprised. from reading, it seems like this maybe is a common problem with shimano brake pads? They are also of unknown age (came with the 1988 bike, probably replaced since then but who knows).
Anyway, they are like Amazon.com : Shimano BR-5700-L RC55C3 Cartridge Brake Shoe Set (Road) : Bike Brake Pad Inserts : Sports & Outdoors those ones except they dont have the second screw to replace the pad (i.e. the pad is one with the cartridge as far as I can tell). I was reading that kool stop salmon's dont seem to have the same metal consuming problem, but I'm having trouble finding ones that aren't just inserts for reusable cartridges.
Sooo what I was wondering was
1) is it a shimano problem, or maybe just old brakes? or could I get away with purchasing, say, this set: Amazon.com : Shimano BR-5700-L RC55C3 Cartridge Brake Shoe Set (Road) : Bike Brake Pad Inserts : Sports & Outdoors with the added bonus that I could use modern brake inserts afterward?
2) if it is a shimano problem... does this kool stop for dura ace/ultegra include the cartridge? Amazon.com : Kool Stop Bicycle Brake Pads : Bike Brake Pad Inserts : Sports & Outdoors They only have a pic for the continental version so I'm not sure
3) otherwise, is there a place to buy reasonable priced 105 (1050 era late 80s) compatible shoe holders so I could get some kool stop inserts?
